BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 288,253, dated November13, 1883.

Application filed January 12, 1853.

' To all whom it may concern.-

Be itknown that I, losnrn B, Mower, a citizen of the United States,residing at Mansfield, in the county of Richland and State of Ohio, haveinvented certain new and useful Improvements in Brick-Machines; and I dohereby declare the following to be a full, clear, and exactdescriptionof the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention relates to an improvementv in brick-machines; and itconsists in the elements hereinafter described, and specifically pointedout in the claims.

The object of the invention is to produce perfect pressed bricks in amanner and by mechanism which will permit of their being produced in. asrapid and economical a way as the present common molded bricks aremanufactured.

The invention will be fully understood by the detailed descriptionhereinaitenpresented, reference being had to the accompanying drawings,in which- Figure 1 is a central vertical longitudinal section of amachine embodying the elements of the invention; and Fig. 2 is a topView,

partly in section, of same.

A denotes the frame of the machine, which frame will be preferablyconstructed of heavy timber and suitably secured to form firm bearingsfor the mechanism employed in the construction of the machine.

Between the upper and lower portions of the frame, and at the right-handend thereof, is secured the vertical shaft B, and upon this shaftismounted the mold-wheel G, the collar (No model.)

also be of sheet-steel. The pieces of sheetsteel G, forming the liningsof the mold, will be secured by bolts H, and the partition F will besecured by bolts 1, clamping its outer edges beneath the mold-table andat each side of the mold, as indicated in Fig. 2.

The base of the molds E consists of the followers U, formed of metalhaving a horizontal surface and depending vertical portions V, asindicated in section in Fig. 1. The followers project a suitabledistance below the table 0, to be acted upon by the mold-ejector cam andtable, hereinafter described. I

Upon the periphery of the mold-table will be secured, at regularintervals, the blocks J, in the present instance eight being employed.The purpose of the blocks J is to control the movement of themold-table, as hereinafter described. v

Over the right-hand portion of the moldtable 0, and arranged to comedirectly over the molds as said table is revolved, is secured thepug-mill K, which is adapted to receive the clay after it has beenground and mix and temper it.

The pugmill K consists of a cylindrical casing or shell having a centralvertical hollow shaft, L, provided with subordinate'radiating arms M,the shaft being hollow and the arms perforated. The upper portion of theshaft L passes through a suitable crossbar, N extending across the topof the mill, thence through the gear-wheel O and bracket I, and,

has its upper extremity set in the packingbox Q, which is adapted topermit the rotation of the shaft L, and at the same time to have asteam-tight joint.

Leading through the packingbox Q into the upper end of the shaft L isthe steam-supply pipe R, by means of which a current of steam isinjectedinto the pipe L,whence it issues through the perforations in thesubordinate arms M, and serves to moisten or temper the clay. w

The beveled-gear wheel above mentioned mesheswith the pinion S, securedupon the shaft of the band-wheel T, and thus,when the said band-wheel Tis revolved, motion will be communicated through the said pinion andbeveled-gear wheel to the hollow shaft L, the

it in a suitable condition to enter the molds and be formed into bricks.

At the under side of the mold-table O, and at a point opposite to thepug-mill K, is arranged the mold-ejector W, which consists of the cam X,mounted upon the horizontal shaft Y, the small wheel Z, and theframe a,which encompasses the said wheel Z and shaft Y, as indicated in Fig. 1.At the proper time in the operation of the machine, after the materialin the molds has been pressed, a revolution of the shaft Y causes thecam Xto turn upward, which forces the wheel 0 and the frame or table aupward. The upward movement of the table or frame a carries the bases UU upward, whereby the pressed bricks are forced upward out of the moldat a point about on a level with the upper surface of the mold-table 0.

To the left of the mold-table G are arranged the vertical shafts b b,upon which, adjacent to the upper surface of the mold-table, aresecured, by suitable collars and screws, the horizontal arms a, whichsustain the lower ends of the shafts d d, upon which is mounted theslide e, carrying on its lower portion the dies f f, which are ofsuitable size to fit the upper edges of the molds E when in operation,and serve 'to press the material to form the brick. The slide 6 has afree vertical movement upon the rods d, and is operated through thetoggled levers 9, one of which is connected with'the lower portion ofthe slide, the other with a' lug on the collar h, hereinafter described,the two extending ends of the toggled levers being connected to one endof the lever i, the other end of which is secured in the upper end ofthe lever j, said last-mentioned lever being eccentrically secured tothe gearwheel 7:. In the upper end of the lever j is also secured oneend of the lever Z, the other end of which is secured in the bearing m,attached to the side of the frame A.

It is obvious that the revolution of the gearwheel kwill be communicatedthrough the two sides of the toggled levers to cause the slide 0 to havea free vertical movement upon the rods d.

The upper ends of the vertical shafts (1 extend through the side of theframe A, being secured at the upper end by a nut and at the lower sideof the frame by the block h, which is secured in place by the bolts,whereby firm bearings are formed. I

Upon the upper surface of the mold-table O, and arranged to cover aboutone-fourth of the circumference of the same, is arranged the frame n,which consists of the V shaped arms 0 0, radiating from the verticalshaft B, and sustaining in their ends the bent bars 10, connected by theround cross-bars q. The frame n will be inclosed by a casing, 15,arranged over the mold-table, and being about four inches in height.directly upon the mold-table. The purpose of the frame n, arrangedwithin the casing t and over the molds E at one side of the pugmill K,is to fill the molds with the material.

The lower edges of the casing it rest The cross-bars q of the frame amove through the clay close to the upper surface of the molds, and serveto compact by their reciprocating movement-the clay into the molds,whereby all the parts of the same are filled with the material beforethe table is moved from under the frame. The frame it gets itsreciprocating movement from the connecting-rod r, the end of which issecured to the crank 8, connected with shaft u. The revolution of theshaft it operates to draw the rod 1" back and forth, which movement iscommunicated to the frame a, with the result hereinbefore described.

Upon the outer end of the shaft 10 is placed the crank-wheel w, to whichis eccentrically secured oneend of the connecting-rod y, the other endof which is secured to the slide 2, as indicated in Fig. 2. The slide 2is encompassed by the casing A, which is secured to the standard 13' ofthe frame A. When the shaft to is rotated, the crank-wheel so willimpart reciprocating movement through the rod 3 to the slide 2, which,through the spring part 0, will cause an intermittent rotation of themold-wheel O. The free end .of the springbar 0 impinges the periphery ofthe moldtable and comes in contact with the blocks J, hereinbeforedescribed, as shown in Fig. 2. The reciprocating movement of the slide 2toward the left of the machine forces the springpawl 0 against the blockJ, which is incontaot with its end, and causes the mold-table to rotateone-eighth of a revolution, v whereby another mold is carried beneaththe pug-mill K, and a full mold is brought'in a direct line below thedies f f. The blocksJ are arranged with such relation to the spring-pawlO and the slide 2 that each full movement of the slide will cause themold-table to revolve oneeighth of a revolution. The timing of the slide2 and the movement of the table 0, as well as the timing of the otherparts of the machine, may be varied at will, according to the number ofmolds em- IIO ployed, the size of the machine, and other v teeth ofwhich mesh with the teeth of the gearwheel 70, to whichthetoggled levershereinbefore described are connected. Upon the shaft w is also securedthe band-wheel G, to which power is applied for setting the'machine inop eration. Motion is communicated through the wheel G and shaft to tothe band-wheel D,

and thence to the band-wheel T, whereby the.

- which levers is to impart vertical reciprocating movement to the slide6 and dies ff, the

effect of which vertical movement of the dies f will be hereinafter setforth.

Upon the shafts: is mounted the geanwheel H, which meshes with theintermediate gearwheel, I, which latter wheel meshes wit-h the wheel J,mounted upon the end of the axle Y, carrying the ej ector-camX. When themachin e 4 is in operation, movement is also communicated from the wheelG through the shaft a, pinion F, gear-wheel k, shaft to, and gearwheel Hto the intermediate gear-wheel, I, and the gear-wheel J, which in turnimparts motion to the shaft Y, and thence to the ejector-cam X, wherebysaid cam is made to elevate or descend and to eject the pressed brickfrom the mold or to permit the bases of the mold to lower, in order toreceive a fresh supply of material from the pug-mill.

The operation of the machine is as follows: The clay, after beingground, is placed in the pug-mill K, and steam admitted through the pipeB to the hollowshaft L and its subordinate arms M. The machine being setin motion, as hereinbefore described, the hollow shaft L will revolve inthe mill, and its action, in connection with the steam issuing from itssubordinate arms, will thoroughly mix and prepare the clay for themolds. The clay leaves the mill at its lower end and enters the moldE,which is directlybeneath it. After the said mold has been filled, themovements of the machine, as before stated,will cause the said mold topass from under the mill and beneath the frame n, the effectof which isto pack the clay in the mold, as above set forth. This movement ofthemold away from the mill will bring another mold below the same. whichwill be filled, and the mold-table will then take another one-eighth ofa revolution,carrying this mold away from the mill and conveying anotherone beneath it. In this manner the molds are filled, and the table hasan intermittent movement, which brings a full mold directly between theshafts (Z d and directly below the dies f f, while an empty mold isbeing filled with clay at the opposite side of the mold-table. At thetime when the mold comesbeneath the dies f f the revolution of the gearis will, through the toggled levers, cause the dies to descend upon theclay in the mold and thoroughly press it into a solid, compact form,whereby two bricks of the best quality will be formed. The continuingrevolution of the gear-wheel It causes the toggled levers to elevate thedies from the mold in which the clay has just been pressed. Themold-table will now take anotherone-eighth of a revolution, which willbring the mold containing the two pressed bricks above the cam-ejectorX, which at this time will turn upward, elevating the bases of the moldand ejecting the two pressed bricks, which will be removed from themachine by a suitable conveying belt or otherwise. At every oneeighthofa revolution of the mold-table Othe dies ff will descend, pressing twobricks, and an empty mold will be filled with clay from the pug-mill.
